T0 ft// whom, t 711,/1/ 1/ concern:

Be it known that we, FRANK OHATFIELD and JAMES S'rRUTnERs, ofMinneapolis, Hennepin county, Minnesota, have invented certain new anduseful Improvements in Attachments for Fleecing or Napping Machines, ofwhich the following is a specification.

Our invention relates to devices adapted for use in connection with amachine for l'leecing or napping a tubular fabric, such as is used inthe manufacture of fleecelined garments. Y

The object of our invention is to provide means for changing the bend orfold in the fabric at the edges to avoid over napping or fleecing atthat point as the material passes through -the machine. A

The invention consists generally in a mechanism or device for moving thefabric laterally to present a new surface at the point where the bend orfold is made at the edges of the flattened tube.

In the accompanying drawings, forming part of this specification,Figurel is a sectional view of a portion of a napping-machine with ourinvention applied thereto. Fig. 2 is a front view of the same. Fig. 3 isa plan view showing a board or plate with the shifting devices'mountedtherein. Fig. 4 is a similar view of a modification adapted for useparticularlyT when the invention is employed independently of thenapping-mm chine. Fig-5 is a sectional view on the line :E no of Fig. 4.Fig. 6 is a sectional view on the line y y of Fig. 3. Fig. 7 is a detailview of the modified means of mounting the shifting devices in thesupporting board or plate. Fig. 8 is a sectional view on the line 2 2 ofFig. 7.

In the drawings, 2 represents the frame of a napping or fleecing machineprovided with shafts 3, 4, 5, and 6 and with rolls 7, S, 9, and 10,around which the fabric passes to the napping-wheels 11. These parts allcorrespond substantially to the shafts, rolls, and napping-wheels of amachine of this type in general use and need no detailed descriptionherein.

We have found in the operation of this machine that the edges of thefabric have a tendency to sag as they pass over the napping-wheels,resulting in an overnapping of the fabric at the point where the bend orfold is made. To obviate this objection in the use of a machine of thistype, we provide a plate 12, having, preferably, rounded corners on oneside and gradually increasing in thickness from that side toward'theother.

Openings 13 are provided in the plate 12,

wherein brackets 14 are secured and provided with studs 15 and 16,projecting into the said openings and having oppositelyturned ends uponwhich toothedidle wheels 16 and 17 are journaled. These wheels, asclearly shown in Fig. 6, are arranged in pairs, one of them at each endof the board lying in a plane substantially parallel with thecorresponding wheel at the other end and the periphery of one wheel ateach end of the board projecting outside the surface of the board toengage the fabric passing thereover. Two of the wheels will projectabove the upper surface of the plate and the other two depend below theunder surface, and all of the wheels are arranged to revolve in planesat an angle to the direction of movement of the fabric. The result isthat when the wheels contact with the cloth, the teeth havingslightly-beveled points, as indicated in Fig. 3, thc fabric will beshifted slightly, moving laterally a sufiicient distance to change thebends or folds at the edges and present a new surface at that point. Theplate 12 is loosely thrust into the tubular fabric, as indicated in Fig.1, and the material allowed to slide over the shaft 3, between which andthe shafts 4 our invention is placed. In some instances, particularly innapping a heavy fabric, we prefer to employ a device consisting of arack 18, having notches 19 to receive a rod 20, over which the fabric tobe napped is carried. This rod can be raised or lowered, according tothe weight of the material to be treated. We sometimes prefer to movethe fabric laterally a greater distance than at other times, and thismovement can be varied by altering the position of the rod 20.

In Figs. 4 and 5 we have shown a modified construction, which consistsin providing a series of toothed guide-wheels 21 and 22, projecting uponopposite sides of the plate 23 and revolving in planes parallel with thedirection of the movement of the fabric. In front of these guide-wheelswe provide a series of toothed wheels 24 and 25, projecting uponopposite sides of the plate 23 and arranged to revolve in planes at anangle to the direction of movement of the fabric, resulting in ashifting1 of the fold or bend during the passage of t e material. Thismodification is designed particularly for use when the invention isemployed independently of a napping-machine.

In Figs. 7 and 8 we have shown a plate 26, having a circular hole oropening 27, wherein a bushing 28 is fitted. Each end of the bushing isprovided with an annular recess 29, adapted to receive a spring 30,having an outwardly-turned end 31, that fits within a socket 32 in thebushinor and is prevented thereby from accidenta movement. other end ofthe sprin is inwardly turned toward the center lof t e hole 27 and formsa` pivot for a bevel-edged wheel 33, Whose periphery projects beyond thesurface of the plate 26 and is adapted to revolve in the plane at anangle to the direction of travel of the fabric. One of these wheels ismounted on each spring, and there is conse uently one on each side ofthe plate 26. T e opposite corner of the plate 26 is equipped withwheels and supports therefor corresponding to those shown in Figs. 7 and8.

In this application we do not wish to confine ourselves to anyparticular construction or' arrangement` of these shifting devices, asthe same are capable of various modifications without departmg from ourinvention.

We claim yas our invention- 1. The combination, with a fleecing ornapping machine, of means for shifting the position of the folds orbends in the tubular fabric as it passes through the machine.

2. The combination, with a eecing or napping machine, of mechanism forimparting a The v lateral movement to the tubular fabric at the pointwhere the bend or fold is made therein, for the purpose specified.

3. The combination, with a fleecing or napping machine, of devicesoperating in planes at an angle to the direction ,of movement of thetubular fabric, and arranged to engage the same and move the materiallaterally at the point where the bend or fold is made therein.

4. The combination, with a iieecing or napping machine, of toothed idlewheels engaging the tubular fabric, and arranged to revolve in planes atan angle to the direction of movement of the fabric and engage the sameto shift the position of the folds or bends therein.

5. The combination, with a fleecing or na ping machine, of a suitablesupport, i le Wheels arranged in pairs on said support, and havingtoothed peripheries projecting beyond the surface of said support uponeach side, arranged to revolve in planes at an an- Ole to the directionof the movement of the lfabric through said machine.

6. A device of the class described comprising a plate having openingstherein, brackets secured in said openings, idle wheels journaled onstuds in said brackets, there being a pair of wheels at each end of saidplate, one wheel on each pair revolving in a plane parallel,substantially with the corresponding wheel of the other pair and at anangle to the other wheel of the same pair, and sald wheels rojectingbeyond the surface of said plate, for the purpose specified.

7. The combination, with means for moving a tubular web or fabric lenthwise, of means for shifting the' position o the bends or folds in thefabric during such lengthwise movement.

In witness whereof We have hereunto set our hands this 30th day ofAugust, 1904.
